The gardaí and Dublin Bus have joined forces to launch an August Bank Holiday Weekend campaign to raise awareness of safety among pedestrians.
Posters with advice for pedestrians will be placed adjacent to the exits in all Dublin Bus vehicles, warning bus passengers: 'Don't be hasty, get across safely'.
343 pedestrians were killed on Irish roads between 2004 and 2008.
This accounts for 20% of road fatalities over the period.
